Firmata | Firmata pure Java implementation | Machine Learning library

I wrote this code which brings Bitcoin's price from CoinMarketCap through its API.
Then it prints the price in the terminal and also sends it to Arduino so I can see it on an LCD Display live (thanks to Firmata library)
It works fine but the problem is that the price does not change, it prints always the same price of when I start the code.

I am trying to use the HC-SR04 and utilize the results in a python script. For this I using the StandardFirmata.ino sketch from: https://github.com/jgautier/arduino-1/blob/pulseIn/examples/StandardFirmata/StandardFirmata.ino

When I try to upload the file to my Arduino UNO I get an error.

How do I fix this error? Is there an alternative version of Firmata I can use that still supports .ping()?

Recently I've been trying to use a wired Xbox 360 controller to interface with my Arduino Uno (via Processing) that I'm using in a test circuit to control two brushed motors. I came across this video that uses the library to control a single servo motor along with videos made by the library's author. I made a few modifications to the code (from the first link) just to support the two motors, and it works (sort of). The only problem is that it accepts input from my Bluetooth mouse instead of the Xbox controller which are both connected to my laptop's USB ports. I set the text configuration file so that "Button 0" and "Button 2" -which correspond to the A and X buttons respectively- make two pins on the Arduino go high which feed into the bases of two transistors that control the motors. Instead, the left mouse button and scroll wheel button on my Bluetooth mouse controls these outputs.

I'm a bit confused about why this is happening and I've tried a few different things to resolve the issue. I thought that when creating the configuration file (with a program that comes with the library) I accidentally choose my mouse as the input device, so I made another configuration file just to make sure that this wasn't the case, though I'm not exactly sure what in the configuration file indicates the correct device to use. Maybe I'm missing something extremely obvious, I just know that I need a second set of eyes to look things over for me. If you have experience with this library your help would be much appreciated, thank you.

Currently I am trying to copy "GeorgeNotFound" 's MinecraftShocker plugin from his Video (https://youtu.be/rCyJ-TFFxWA) but i am getting this error which means no Arduino is found right?

I already checked the Arduino Uno is connected to "COM3" and I already have the Firmata installed on the Arduino.

I'm using Maven to add libraries.

I changed the jar i was using from slf4j-log4j12.jar to slf4j-jdk14.jar and now i get a different error.

Added text to indicate where it keeps failing.

Made all earlier Edits Italic for better readability.

I am not using the slf4j-jdk14.jar anymore, Instead I removed the dependencies of org.scream3r:jssc:2.8.0 in com.github.kurbatov:firmata4j:2.3.8 and istalled io.github.java-native:jssc:2.9.2 separately (so it now doesn't use the 2.8.0 as default anymore, but instead is using the fixed 2.9.2 version ;) ) And voilà it's working

What is the best way (in Python) to convert 32-bit signed longs to 7-bit ints, in order to transmit them via Firmata/serial link? Converting into 8-bit is not a problem, just (long_val).to_bytes(4, 'little'). The final sequence should be like this:

Good Night, My Arduino has the example program of Firmata running on it, StandardFirmata, and I made a program in Processing using Firmata and a library called Game Control Plus. My program takes the values ​​of the PS4 joystick and converts them into numbers that the Firmata passes as commands to the Arduino and everything seems to work well, however, for some reason, the left and right servo motors do not perform numbers under 90 and even sometimes they stop when executing movements. First thing I thought was that the engines were forcing or that the program was sending the wrong values, so I made a simple Arduino program for the servo and they can execute values ​​under 90, and I also did the processing print on the screen the values ​​he was passing and the values ​​are going correctly. Anyway, I will leave the code and the wiring diagram I made below. I hope someone can help me solve this mystery.

I have Flask app and within the app, I have a view where I am using xlsxwriter to write and save Excel file. When I run the app locally it works perfectly. When I deploy it all the views work except the one where I am writing the Excel file, it gives me Error 500. In the logs I was that the error is that I am trying to start the file with function that is only for windows, can someone tell me how to start the file or download it? I don't need it to be stored in a database or cloud storage, just to be printed or downloaded immediately. P.s Please excuse me if I have made a mistake asking this question.
